Reasons to do the IMC ? You live in the UK
I decided to start mine after reading the 78 seconds thread a while back.
The first minute after the foggles go on is definitely the minute in which you'd put yourself in most danger if you were a PPL entering cloud inadvertently.
It's one thing reading about 'The leans' , but another entirely when you're suddenly convinced that you're diving and turning all at once, all instrumentla evidence to the contrary.
Mind you, you can feel a bit of a muppet when everyone is posting on here about what a great gin clear day it was ("There I was over Milton Keynes watching the traffic going in and out of Galway") and all you've seen is the instrument panel and possibly only half of that.
